Copp, Jr., Dayton, Ohio, assignor to General Motors Corporation, Detroit, Mich., a corporation of Delaware Filed Mar. 11, 1966, Ser. No. 533,471 9 Claims. (Cl. 62-262) This invention pertains to window air conditioners for horizontal, sliding windows.

Window air conditioners were first applied to conventional vertical sliding double hung windows. Many have been sold for such installation. The application of window air conditioners to other types of windows has been more difiicult. Heretofore, no fully satisfactory arrangements have been proposed for installing window air conditioners in horizontal sliding windows even though such windows have been popular in home construction for many years.

It is an object of this invention to provide a window air conditioner for horizontal sliding windows having a minimum of interference with the normal use and the transmission of light by the window.

It is another object of this invention to provide a window air conditioner for horizontal sliding windows which will reduce to a minimum the area of glass which is covered or obstructed by the air conditioner.

These and other objects are attained by constructing the air conditioning casing as illustrated in the drawings with a deep notch extending inwardly from one side sufliciently wide to receive both sliding windows or the wall at the side of the window. The narrow but high neck portion of the cabinet at the inner end of the notch may be fixed or adjustable to vary the width of the'notch to accommodate varying thicknesses of the walls or windows.

The refrigerant conduits and electric conductors extend through the neck portion connecting the condenser, compressor and fan in the outside part of the casing with the evaporator, fan and controls in the inside portion of the casing.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings wherein preferred embodiments of the present invention are clearly shown.

In the drawings:

FIGURE 3 is a vertical sectional view taken along the lines 33 of FIGURE 2;

FIGURE 4 is a horizontal sectional view similar to FIGURE 2 with the parts of the refrigerating system omitted showing the application of the air conditioner t0 the wall at the side of the sliding window;

FIGURE 5 is a side view partly in section taken along the line 5-5 of FIGURE 4; and,

FIGURE 6 is a fragmentary vertical section taken along the lines 66 of FIGURE 4.

Referring now more particularly to FIGURE 1, there is illustrated a window type air conditioner resting upon 3,309,889 Patented Mar. 21, 1957 the window sill 22 of -a horizontal sliding window having the sliding wind-ow sashes 24 and 26 (shown in dot-dash lines) which slide horizontally in suitable grooves upon the sill 22 forming a part of the window frame 23. Th air conditioner 20 includes a cabinet or casing having an inner portion 28 extending from the window into the room having an inlet air grille 30 and an outlet air grille 32 in the front of the cabinet. This inner portion 28 also has control knobs 34 and 36 for shutting the air conditioner ofl? or turning it on and for controlling the fans and dampers. These controls may be similar to those illustrated in Patents Re. 22,303 issued Apr. 20, 1943, and 2,472,792 issued June 14, 1949. The air conditioning casing also includes an outer portion 38 extending outside the room or building wall 40 having side air inlets 42 and a rear outside air discharge grille or louvers 44. The casing is provided with a deep notch 46 extending inwardly from the left side for receiving substantially all of the window sash 26 and whenever necessary, as much of the window sash 24 as desired. This permits the opening and closing of the window 24 or 26 whenever desired without any substantial interference from the window air conditioner since the window sash can freely move into and out of the deep notch 46. The outer portion at the inner end of the deep notch 46 has a narrow neck portion 48 formed integral with it extending into the inner portion 28 as is illustrated in FIGURES l and 2. The side of the wall 40 may be provided with a gasket seal 50 between it and the adjacent side of the neck portion 48. The edge of the window sash 26 may likewise be provided with a gasket seal 52 for making a seal with the inner face of the neck portion 48. Above the neck portion 48 there is provided a filler panel 54 which is held between the adjacent edge of the wall 40 and the adjacent edge of the window sash 26 extending upwardly from the top of the neck portion 48 to the top of the window sash 26. This provides an adequate seal to prevent air leakage through the window opening when it is provided with my air conditioner. The filler panel 54 may be transparent or translucent, if desired.

The narrow neck portion 48 is integral with the outside portion 38 of the casing and extends in the form of a rectangular sleeve 56 into the inner portion 28 which is located in the room to be cooled. The sleeve 56 and the casing 38 may be further strengthened wherever necessary by the use of the angle iron framework 58 which is provided along the top and bottom edges of the various walls. The inner portion 28 likewise is provided with a supporting angle iron framework 60 along the top and bottom edges of the walls forming a sleeve 61 which slidably receives the rectangular sleeve 56 as illustrated particularly in the FIGURE 2. The rectangular sleeve 56 can slide into the inner portion 28 various distances to vary the width of the deep notch 46. The adjusted position of the rectangular sleeve 56 relative to the inner portion 28 may be held through the use of bolts extending through apertures and slots in the side walls as illustrated I in FIGURES 46.

The outer portion 38 contains a propeller type fan 62 positioned within the shroud 64 driven by the fan motor 66 for drawing air in through the air inlets 42 in heat transfer relation with the sealed motor compressor unit 68 and discharging the air in heat transfer with the condenser 70 through the air outlet 44. The

inner portion also includes a fan 72, preferably of the centrifugal type, driven by an electric motor 74 for drawing air in through the air inlet 30 in heat transfer relation with the refrigerant evaporator 76 and discharging the air through the air outlet 32 into the room. The sealed motor compressor unit 68 withdraws evaporated refrigerant from the evaporator 76 through the flexible suction conduit 78 which extends through the neck portion 48 to the inlet of the sealed motor compressor unit 68. This suction conduit 78 has a long lateral extending portion within the inner portion 28 which will allow the inner and outer portions 28 and 38 to be moved further apart to increase the width of the notch 46. The refrigerant drawn through the suction conduit 78 is compressed in the sealed motor compressor unit 68 and forward through the supply conduit 80 to the inlet of the condenser 70. The outlet of the condenser 70 is connected by a capillary restrictor supply conduit 82 to the inlet of the evaporator 76. This capillary supply conduit '82 is flexible and has a serpentine loop portion 84 sufliciently long to flex and allow the outer portion 38 to be moved further away from the inner port-ion 28 to increase the width of the notch 46. A transverse wall 95 is provided at the inner end of the rectangular sleeve 56 to separate the inner and outer portions 28 and 38. For exhaust or ventilation it may be provided with a pivoted door -97 (FIGURE which may be opened by a knob.

The neck portion 48 may be supported upon the bottom by a pad 86 resting upon the sill 22. This pad may be made of any suitable resilient rubber-like material such as natural or synthetic rubber. The outer portion 38 may be provided with a threaded adjustable screw type support 88 located in the inner corner opposite the neck portion 48 extending down to and being supported by the sill 22. The inner portion 28 may also be provided with a threaded adjustable screw type support 90 extending down to and being supported by the sill 22. If desired, the space between the two window panes 92 and 94 in the sash 26 and 24 may be filled by a sponge rubber strip 96 to prevent leakage of air into and out of the room at this place. This however, will not interfere with the opening of the sash 24 and also will allow the movement of the sash 26 for cleaning and ventilation.

In the form shown in FIGURE 6, my air conditioner is applied to the sliding window in a different manner. Both of the window sashes and the window still are similar to the window sill 22 and the window sashes 24 and 26 shown in FIGURES l3. In this form the refrigerating system is omitted but preferably is similar to that illustrated in FIGURE 2. In this application, the casing or cabinet has the adjustable neck portion 48 resting upon a resilient support pad 86 which in turn rests upon the Window sill 22. In this arrangement however, the neck portion 48 is lodged against the extreme left side of the Window frame 23 and sealed by a gasket 130 on the left side of the window frame. The window sash 24 has a sealing gasket 13'2 providing a seal between the sash 2-4 and the side of the neck portion 48. Above the neck portion extending to the top of the window frame 23 is a rectangular filler panel 134 which extends bet-ween the adjacent side of the window sash 24 and the adjacent side of the window frame 23. This tfiller panel i134 may be transparent or translucent if desired. This completes the seal for preventing the flow of air from the outside into the room.

Integrally connected to the neck portion 48 is the larger outer portion 38. This larger outer portion contains all of the portion of the refrigerating system contained in the outer portion of FIGURE 2 including the sealed motor compressor unit 68, the condenser 70, the fan 62, the shroud 64 and the fan motor 66. These are not shown to avoid unnecessary duplication. The two sleeve portions '56 and 6-1 are provided with suitable slots and apertures for receiving the clamping bolts 148 and 150 which extend through the side walls. Similar clamping bolts are provided in a similar arrangement for the cabinet shown in 'FIG-U R-ES 1-3. The inner portion 28 includes an evaporator 76, fan 72 and the fan motor 74 like those shown in FIGURE 2.

The deep notch 46 extending inwardly from the left side to the neck portion 48 receives the wall portion 40 extending into the notch 46 from the left side and extending to the left side of the window frame 23. It will be seen that in this arrangement the air conditioning cabinet only obstructs the portion of window equal to the cross sectional area of the neck portion 48. If desired, the filler portion 134 may be made of translucent or transparent material so that the light is substantially unobstructed by reason of installation of the air conditioner within the window frame 23. By the provision of the deep notch 46 only the wall 40 is covered by the major portion of the air conditioner. This, therefore, provides an arrangement whereby the sliding window is substantially free for normal use since they may be moved horizontally for cleaning or ventilation with only the narrow neck portion 48 limiting the movement of the window sash 24 at the left edge of the window frame 23. Since this amount is very small, the window remains available for substantially all normal use thereof.
